Abstract

Modifications in the field of shipping would have become commonplace especially shipbuilding in Indonesia. This is one way of turning a ship to be able to function in accordance with the needs or even just to change so that the appearance of the vessel more attractive, convenient, and can generate more profits for their owners. Not infrequently, the modification is done by changing the total of ships or in part so that the function, form, and even the general requirements of the ship can be changed.
One modification is the Rampdoor ship where rampdoor is one tool to optimize the work processes that occur on the manifold ferry boats to be able to load the vehicle and its passengers. Rampdoor modifications done on the ship because the ship had to adjust the condition of the port that will be the operation of the path or trajectory path of the ship. But before making modifications, necessary considerations - considerations do so when the operation of the ship is done to avoid problems that can result in losses both for transport users boats, crew boats, along with the owner of the vessel.
From the results of the consideration obtained some considerations that arise namely Aspect and Aspect Ship Stability Volume Vehicles that can be accommodated. Of the various aspects of the emerging aspects of the stability of the ship so that difikirkan because this aspect is an aspect that is vital to the ship. But this kind of thinking, so that the stability of the ship does not change signifisikan namely by taking into account the weight of the construction on the part of the ship to be cut and then the weight of the construction rampdoor equilibrated with designs that will be planned.
